36. Identifying regions for asymptotic expansions in QCD

Yao Ma (ETH Zurich)

The method of regions, a systematic approach to the asymptotic expansions of Feynman integrals, suggests that a Feynman integral can be reconstructed by summing over integrals expanded in certain regions. This technique not only facilitates the computation of Feynman integrals but also provides valuable insights for formulating an EFT, such as the Soft-Collinear Effective Theory (SCET)....

22. Resummation of small-momentum logarithms for lattice calculation of GPDs in the large momentum effective theory

The generalized parton distributions (GPDs) provide important information for 3D imaging of the proton in the longitudinal momentum fraction $x$ and transverse impact parameter space. Recently, thanks to large-momentum effective theory, they can be directly calculated in lattice QCD from the so-called quasi-GPDs. In the perturbative matching of quasi-GPDs to GPDs, there are logarithms related...
